Made with Xara. The dominating house type was the X-joint log house knuttimmerhus — houses built with horizontally laid logs, interlocked in the corners. Sweden has large woodlands so the conditions were right for constructing log houses. Other terms are notched corners; log built corners or corner joints. History X-joint log houses have been around for a very long time in Sweden. The X-joint building technique began most likely during the 11th to 12th century. The oldest documented evidence of x-joint log houses in Sweden is from the 13th century. The tradition of building X-joint log houses probably started in the cities and then spread to the countryside. Some historians claim that the Vikings — were building X-joint log houses but there is no verified evidence of that. The X-joint technique spread from Eastern Europe to Scandinavia and the time frame for this is probably the 11th century.

Joinery is a part of woodworking that involves joining together pieces of wood or lumber, to produce more complex items. Some wood joints employ fasteners, bindings, or adhesives, while others use only wood elements. The characteristics of wooden joints – strength, flexibility, toughness, appearance, etc. Therefore, different joinery techniques are used to meet differing requirements. For example, the joinery used to construct a house can be different from that used to make puzzle toys, although some concepts overlap.
The proposed modelling approach represents a beam-column joint schematized with shell elements for the wooden parts and non-linear one-.
If you have ever been to Europe, most likely, you also visited a hundreds of years old castle dating back to the Middle Ages. All those turrets and high walls took your breath away and, duly impressed, you retired for some refreshments to the local pub down Castle Street. As you were writing your postcards and chatting away with your fellow tourists about the magnificence of the ancient architecture, little did you know you were, in fact, sitting under the roof of one!
In fact, these buildings might be just as old as the nearby castles and churches, but instead of dominating the landscape, they mold into it. Even though their roofs might have burned down in constant skirmishes between feudal overlords, or their walls destroyed in an explosion during one of the World Wars, their joints were hand carved and fitted to last. Of course, Europe is only one of the places where timber frame construction goes back centuries.

Timber framing is a nearly obsolete system for creating the structural skeleton of a house. Timber framing was used in Europe since medieval times, and is the basis for English half-timbered houses where the structural timbers show on the filled and stuccoed exterior. In a timber-frame building, the entire weight is carried by massive beams and posts; wall sheathing is just a curtain to keep out the elements.
Timber framing was the basic technique for building wooden houses in the U. The timber frame was hand hewn. In the early days, all of the framing timbers were felled and squared up by hand. Even after the advent of power sawmills made it possible to make square timbers by machine, all of the notching for the rather sophisticated joinery was still done by hand. Housewrights would develop their own special cuts for making joints and connecting timbers; the old houses have ingenious combinations of mortises and tenons, dovetails, and other joints.
But there are telltale signs inside. The posts and summer i. These massive timbers were often encased in smooth planed boards with beaded edges.
T imber frame construction is one of the oldest forms of construction that remains in existence today. Joints from timber frame structures can be found as far back in history as B. Timber frame structures have been uncovered in archeological sites throughout the Middle East, Europe and Asia. Europe is full of timber-framed structures dating back hundreds of years, including manors and castles, homes, cabins and inns, whose architecture and techniques of construction have evolved over the centuries.
Joints from timber frame structures can be found as far back in history as B.C. The art of timber framing dates back to some of early man’s first primitive.

Prior to the creation of an English tree-ring chronology in the late s, typology was the main method by which to date a medieval timber-framed structure. Cecil Hewett pioneered buildings typologies for medieval carpentry joints and timber-framed buildings in south-eastern England Gibson and Andrews , online. In , Matthew Johnson warned of relying on typologies to date buildings Johnson , primarily because they are not always reliable and are based on assumptions rather than science.
This Chapter will address some previous errors made under the auspices of chrono-typologies forwarded by the likes of; Henri Deneux, Cecil Hewett and J.
Feb 21, – The traditional method of post and beam framing has always been mortise and tenon, dating back years. Its appeal is that it does not.
How old is my barn? Good question! Probably the most common question asked about barns, and yet one of the hardest ones to answer. Because barns are too much like fences. We build them, or at least we used to, because they serve a purpose. Occasionally you will find a date chiseled in a foundation stone, or carved into a timber, and more commonly you will find a date in the slates on the roof.
These dates can be misleading though. The date stone may actually be the date the barn was raised from a ground barn to a bank barn. The date carved in the timber might be the date the barn was rebuilt after being moved, and more often than not, the date on the roof is the date the slates were installed. Our oldest barns were built in a time when construction itself was a matter of hard work with very basic tools and a wood lot for a lumberyard.
Traditional Timber Framing – A Brief Introduction
Why Do Timber Frames Fail? The fundamental question as to why are ironwork repairs important enough to warrant study can be answered reasonably simply. Iron-work repairs represent the pinnacle of low-tech, minimum intervention repairs to failed timber joints and thus they highlight the inherent failings of the timber, its fabric, construction and properties and the efforts that the craftsmen went to in overcoming its failings.
There are several reasons why timber frames fail and these are summarised following. Given the diversity of joints in timber framing and their steady evolution as highlighted by Cecil Hewett in English Historic Carpentry it is evident that some joints served their purpose better than others.
A joint formed by two boards, timbers, or sheets of wood that are held together by nails, fasteners, pegs, or the like. For specific types of wood joints, see broken.
Customers often ask us questions about dating furniture. One way to do this is from the dovetail joints used in its construction. More often than not the dovetails are age appropriate, and this article will explain what a dovetail is, and what to look for in a period piece to correctly date it. A dovetail is a common type of joint used to connect pieces of wood together. It is commonly used in cabinetry to join the sides of a drawers to the front.
It consists of a series of pins which are cut so they extend from the end of one board, which interlocks with a series of tails cut into the end of another board. The pins and tails are wedge shaped, similar to a jigsaw piece. A finished dovetail joint has great tensile strength and resists being pulled apart. Once a wooden dovetail has been glued it requires no mechanical fastening such as screws or nails.
Hand-made dovetails are slightly irregular, and only really fit in one way, whereas machine cut dovetails are uniform and are often interchangeable from their original order. The dovetail technique is centuries old and can be dated back to ancient Egypt, where it was used in furniture entombed with mummies. Early hand cut dovetails from the 17th century were wide, stubby and crude looking.
